我国上市公司地区分布演变特征及其路径依赖研究

The Study on the Characteristics of Regional Distribution Evolution and the Path Dependence of Listed Companies in China

该文对我国上市公司地区分布演变进行分析发现,我国上市公司覆盖地区越来越广,但分布保持不平衡发展态势,北京、上海、深圳形成了三大全国性集聚中心,省会城市则在省级层面成为各省集聚中心。通过占比差定量分析发现我国上市公司在地级市分布存在明显的路径依赖现象,2000年之后布局基本延续之前的布局特征,在2016年3033家上市公司中,只有151家（占比4.97%）与2000年的布局相比发生了跨组调整。

This paper analyzes the regional distribution of listed companies in China and found that regions with listed companies are increasing,but the distribution is uneven.Three National Centers of Beijing,Shanghai and Shenzhen have been formed initially,the capital city of each province has become the center at provincial levels.Through proportional analysis,this paper finds that the distribution of listed companies at prefecture levels have obvious path dependence phenomena.The layout after the year of 2000 resembles that before the year of 2000.Of the 3033 listed companies in 2016,only 151（accounting for 4.97%）had undergone cross group layout adjustments.
